AI-Generated Summary

In this episode of The CITIUS MAG Podcast, host Chris Chavez sits down with elite marathoner Susanna Sullivan ahead of the 2026 Boston Marathon. Sullivan reflects on her breakthrough 2025 season, highlighted by a fourth-place finish at the World Championships in Tokyo—a result that marked a pivotal shift in her mindset and confidence. She discusses the physical and mental toll of racing in quick succession at New York and London, the importance of recovery, and how her partnership with coach Andrew Gerrard has evolved over six years. With a renewed focus on Boston’s challenging hills and downhills, Sullivan shares her intentional training buildup, including a recent 15K run from the start to the finish line to recalibrate her course feel. She also reveals the excitement of being deeply involved in Brooks’ innovation process, from shoe development to athlete feedback, and reflects on a surprising track 5K experiment that taught her valuable lessons about overconfidence. As she prepares for a race that feels like her first Boston despite having run it before, Sullivan’s goal is clear: to be in the mix with 5K to go and reclaim her streak of top-10 finishes at major marathons.

Key Takeaways
1

Train for Boston not just in miles, but in specific hill and downhill work—intentional course-specific preparation is key.

2

Mindset shifts from 'trying to be in the top 10' to 'believing you can be in medal contention' can transform race performance.

3

Recovery is part of the training process—don’t skip the rest, especially after back-to-back major races.

4

Being involved in product development (like Brooks’ Hyperion Elite shoes) gives athletes a deeper connection to their gear and performance.

5

Use real course simulations (like Wahoo Kicker Run) to rehearse Boston’s terrain at home before race day.
